常見(jiàn)問(wèn)答

科冪反應釜常用材質(zhì)有哪些，代碼分別是什么？

常見(jiàn)問(wèn)答

目前公司常用的材質(zhì)主要為哈氏合金C276與316L不銹鋼，代碼分別為哈氏合金：HC1，316L不銹鋼：SS1。

常見(jiàn)問(wèn)答

簡(jiǎn)述水熱合成反應釜使用注意事項

常見(jiàn)問(wèn)答

水熱合成反應釜使用前請仔細查閱所使用溶劑在反應溫度下的飽和蒸氣壓，確保不會(huì )超過(guò)水熱合成反應釜的最高允許使用壓力。在使用HT系列水熱反應釜時(shí)，因內襯為PTFE材質(zhì)，高溫高壓環(huán)境下有一定的壓縮性，初次使用時(shí)候釜蓋不宜過(guò)度旋緊，避免再高溫高壓下熱漲擠壓導致釜體內膽嚴重變形當水熱釜使用溫度超過(guò)150℃時(shí)，建議擰緊釜蓋前，在螺紋處涂抹一層高溫鋰基潤滑脂，防止高溫下不銹鋼螺紋咬死以下條件禁止使用水熱釜：溶劑的沸點(diǎn)低于60℃，反應過(guò)程產(chǎn)生大量氣體，物料具有易燃、易爆特性或毒性程度為輕度、高度危害

常見(jiàn)問(wèn)答

科冪反應釜有哪些密封形式？分別有什么特點(diǎn)？

常見(jiàn)問(wèn)答

1、增強型PTFE平墊片密封，溫度可達300攝氏度（長(cháng)期）/350攝氏度（短期），增強型PTFE墊片相比于普通白色PTFE材料具有更好地耐高溫性和更低的蠕變性，具有通用的耐化學(xué)腐蝕，榫槽結構可以有效方式PTFE墊片在高溫下因冷留性導致密封失效。 2、石墨平墊片密封。擁有比PTFE墊片更高的承受溫度，設計溫度300攝氏度以上，不經(jīng)常在強氧化性介質(zhì)氛圍下操作，可以采用石墨墊片密封。 3、氟橡膠與全氟橡膠自密封O型圈，結構簡(jiǎn)單，操作方便。但是耐腐蝕性差，使用溫度低 4、金屬硬密封。通過(guò)金屬材料在預緊壓力作用下發(fā)生微小形變的原理，使密封副之間線(xiàn)狀接觸實(shí)現密封，不引入其他材料，介質(zhì)僅與釜體釜蓋的金屬材料接觸。

常見(jiàn)問(wèn)答

科冪機械攪拌反應釜，可選配哪些形式的攪拌槳？分別適用于哪些反應物料？

常見(jiàn)問(wèn)答

為了適應各種工況下的攪拌混合需求，科幕提供多種形式的攪拌槳供選擇?？苾鐧C械攪拌反應釜標配有單層推進(jìn)式攪拌槳，可選配多層推進(jìn)式、錨式、螺帶式、自吸式、組合式等多種形式的攪拌槳，以及催化劑裝載框。它們都通過(guò)螺紋與攪拌軸連接，因此可以方便的實(shí)現互換。

常見(jiàn)問(wèn)答

科冪反應釜主動(dòng)降低釜內的溫度的形式有哪些？各自的優(yōu)缺點(diǎn)是什么？

常見(jiàn)問(wèn)答

目前主要有風(fēng)冷、內冷卻以及循環(huán)油冷三種。風(fēng)冷就是將科冪反應釜放置于通風(fēng)處，通過(guò)風(fēng)帶走熱量，從而達到冷卻效果，這種方式最簡(jiǎn)單易行，但冷卻速率較慢，且受當地條件影響。

常見(jiàn)問(wèn)答

在安裝使用科冪反應釜時(shí)，需要使用哪些標準工具？

常見(jiàn)問(wèn)答

為了方便使用時(shí)對高壓反應釜、水熱反應釜以及其他類(lèi)型的壓力容器的拆裝操作，科冪為每臺反應釜配有科冪專(zhuān)利設計的拆裝助力底座板，它可以通過(guò)螺釘固定在實(shí)驗室的桌面或者其他方便的地方，使用時(shí)，將釜底的定位槽嵌入助力板上，反應釜被固定，就可以通過(guò)一把內六角扳手或者活動(dòng)扳手很方便的擰緊或拆卸反應釜了。

常見(jiàn)問(wèn)答

拆卸高壓反應釜應注意哪些事項？

常見(jiàn)問(wèn)答

首先嚴禁在反應釜處于高溫或帶壓狀態(tài)下緊固或拆卸任何螺栓、接頭，待到反應釜降溫至將近室溫再進(jìn)行拆卸，拆卸時(shí)應穿戴高溫手套。其次嚴禁在帶壓狀態(tài)下進(jìn)行拆卸，防止造成人員損傷。
